A crankshaft for a compressor and manufacturing method of the same are provided to increase applicable area by selecting eccentric position of an eccentric shaft part according to the refrigerant compressing capacity for a compressor to be applied. A crankshaft for a compressor comprises a main shaft part(51), an eccentric shaft part(52), and a weight balance part(53). The main shaft part has one end pressurized into a rotator of a driving unit to transfer driving force of the driving unit to a compress unit. The eccentric shaft part is eccentrically placed at the other end of the main shaft to be connected through a piston of the compress unit and a connecting rod. The connecting rod has one end rotatably connected at the outer periphery. The weight balance part is positioned between the main shaft part and the eccentric shaft part for compensation of rotating imbalance due to the eccentric shaft part. The weight balance part and the main shaft part have an integrated body part. The eccentric shaft part to be manufactured separately from the body part is combined to the one side of the weight balance part to select eccentric position.
